Sound files supporting the PhD thesis "Modelling Railway Rolling Noise"

Abstract

This dataset includes supplementary sound files for the PhD thesis: C Knuth, Modelling Railway Rolling Noise, University of Southampton, Faculty of Engineering and Physical Sciences, 2025 This dataset contains the sound files produced using the numerical models developed during the PhD candidature (2020 - 2025) for listening to synthesised railway rolling noise signals and impulse responses of the railway track. The simulations were carried out by combining the FE model of a rotating railway wheelset with a 2.5D FE/BE model of the railway track in a rolling noise prediction scheme for roughness excitation. Overall 28 sound files are included as .wav files and structured in the folders of the supplemented .zip file. The folders contain the following files: - Impulse response of the rail and sleepers (sound pressure at the receiver for a vertical unit force on the rail head) at distances 0, 25 m and 50 m from the forcing position - Simulated pass-by rolling noise signals of a single wheel on a single rail and the sleepers excited by the rail for a speed of 160 km/h - Simulated pass-by rolling noise signals of a wheelset (two wheels) on both rails and the sleeper excited by the two rails for a speed of 160 km/h - Simulated pass-by rolling noise signals of four wheelsets on both rails and the sleeper excited by the two rails for a speed of 160 km/h - Measured pass-by noise signal of the train for a speed of 160 km/h - Simulated pass-by rolling noise signals of a train (16 wheelsets on both rails and the sleeper excited by the rails) for a speed of 160 km/h for replicating the measurement - Measured pass-by noise signal of the train for a speed of 80 km/h - Simulated pass-by rolling noise signals of a train (16 wheelsets on both rails and the sleeper excited by the rails) for a speed of 80 km/h for replicating the measurement
